Actually, the US is quickly producing several vaccines in high volumes. The US had several vaccines produced, expecting that most would fail. But right now, I think we're looking at 2-3 successful vaccines, with each new one being more easily distributed than the last. On that front, the news has been nothing but good. The Johnson and Johnson vaccine is our trump card though. Once it gets into circulation, it only requires one shot, rather than the standard two.
The first two are, if I recall, already being distributed across the entire country. It's estimated we need only 50% of the population to get the vaccine. Between that 50% and the 25% of people who already had it, we've got herd immunity. The only way this falls flat on its face is if people refuse to get the vaccine. But at this point, employers are already looking at FORCING their employees to get it. Not that it should be too hard, given that your transmission rate drops by 75% if you have it.
COVID-19 already has trouble spreading. It actually spreads quickly through rare jackpots that have huge payoffs. We managed to limit that with masks, social distancing (sort of), and cutting down on immigration. If you throw these vaccines into the mix, things should get better. The companies are even looking to get ahead of the new variants that COVID-19 has produced.
The US will actually be able to regenerate its damaged economy over the summer.
